If air pressure gage indicates 121 to
psi (834 to 889 kPa), no adjustment
necessary, go to Step (16).
(b)
If air pressure gage indicates less than 121 psi (834 kPa) or more than 129 psi (889 kPa) go to Step
(8).
(8)
Remove cap (3) from governor (4).
(9)
Loosen nut (5) while holding adjusting
screw (6).
